Definitions

  • the present disclosure relates generally to devices for use in the filtration industry, and various methods associated with such devices. More particularly, this disclosure relates to a water filter, and various methods associated with water filters and water filtration.
  • Filtration systems are often used to maintain the quality of water in pools, ponds, aquariums, and the like. Outdoor bodies of water, such as pools and ponds, are particularly susceptible to contaminants (e.g., clay, dirt, leaves, grass, pebbles, stones, and other materials) that affect water quality. Filtration systems typically include a filter that traps and contains such contaminants, and a pump that circulates water through the filter.
  • contaminants e.g., clay, dirt, leaves, grass, pebbles, stones, and other materials
  • the present disclosure generally relates to a vortex generator 20 for use in a fluid filter 10, such as a pond filter.
  • the vortex generator 20 is used during back flushing operations to create a fluid vortex within the filter that dislodges particulates trapped by the filter during normal filtering operations.
  • the present vortex generator 20 is designed to increase flow through the filter 10 during normal filtering operations to more efficiently filter water at a desired filtration rate, and maximize the effectiveness of back flushing operations. More specifically and as will be described in greater detail hereinafter, the present vortex generator 20 has openings that increase flow through the filter 10 during normal filtering operations, and a flapper valve that closes the openings to redirect water for the generation of a vortex during back flushing operations.
  • the filter 10 of FIG. 1 is typically used for the filtration of a fluid, such as pond water or aquarium water. While the remaining description refers to the filtration of water, it is to be understood that the present filter can be used in the filtration of other types of fluids.
  • the filter 10 includes a filter housing 12 that defines an interior 50 and a plurality of ports 40, 42, 44. Each of the ports 40, 42, 44 is in fluid communication with the interior 50.
  • the plurality of ports includes a first fluid port 40 that is an input port during normal filtering operations and a second fluid port 42 that is an output port during normal filtering operations.
  • the second fluid port 42 functions as an input port to the reverse backflushing waterflow
  • a third fluid port 44 of the plurality of ports functions as the discharge or output port.
  • the filter 10 further includes a central flow tube 14 located within the interior 50 of the filter housing 12.
  • the central flow tube 14 has a first end 46 located adjacent to the bottom of the housing 12, and a second opposite end 48 that connects to the second fluid port 42 of the housing.
  • the central flow tube 14 provides fluid communication between the second fluid port 42 and the interior 50 of the housing 12.
  • the central flow tube 14 and the housing 12 define an annular filtering chamber 18.
  • Filter media 16 (schematically represented) is located and/or deposited within the annular filtering chamber 18. Water circulating through the filter 10 during normal filtering operations must pass through the filter media 16 before exiting the housing 12 through the second fluid port 42. The filter media 16 traps and contains contaminants as the water passes through the media.
  • the vortex generator 20 is located adjacent to the bottom or first end 46 of the central flow tube 14 and provides all fluid communication between the central flow tube 14 and the annular filtering chamber 18.
  • the vortex generator 20 further defines the only flow passageway between the fluid ports 40, 42, 44 during both normal filtering operations and back flushing operations.
  • the vortex generator 20 creates a water vortex within the filter housing 12 that directs the flow of water in a circular direction within the annular filtering chamber 18.
  • the creation of the water vortex aids in removing particulates trapped by the filter media 16.
  • the vortex generator 20 generally includes a base 22, a plurality of directional flow elements or arms 32, and a movable flapper valve 28 (e.g., flap, control device, or cover).
  • a movable flapper valve 28 e.g., flap, control device, or cover.
  • the arms 32 of the vortex generator 20 extend outward from the side walls 26 of the base 22 in a spiral-like manner.
  • Each arm 32 defines an internal water channel 52.
  • the internal water channels 52 are in fluid communication with apertures 34 formed in the side walls 26 of the base 22.
  • the spiraling arms 32 curve in one direction to create the fluid vortex during back flushing operations.
  • water is directed through the apertures 34 in the base 22, through the water channels 52, and out an aperture 36 located at an end of each spiraling arm 32 to generate the vortex.
  • the flapper valve 28 of the vortex generator 20 when positioned within the filter housing 12, the flapper valve 28 of the vortex generator 20 is positioned at a downstream side (e.g., 56) of the bottom wall 24 of the vortex generator 20 (i.e., downstream in relation to the flow of water during normal filtering operation).
  • the flapper valve 28 includes a tab 38 ( FIG. 4 ) that attaches the flapper valve 28 to the base 22.
  • the flapper valve 28 is constructed to pivot or move between a closed position in which the openings 30 of the bottom wall 24 are covered ( FIG. 2 ), and an open position in which the openings 30 are uncovered ( FIG. 7 ).
  • water enters the annular filtering chamber 18 through the first fluid port 40.
  • the water then flows through the filter media 16, and is returned to the body of water through the central flow tube 14 and second fluid port 42.
  • the flow of water passes through the openings 30 ( FIG. 7 ) of the vortex generator 20 by moving (e.g., pushing or lifting) the flapper valve 28 from the closed position to the open position (as shown in FIGS. 5 and 7 ).
  • the openings 30 of the vortex generator 20 define the primary flow passageway for water flowing through the filter housing 12 during normal filtering operations (i.e., for water flowing from the first fluid port 40 to the second fluid port 42).
  • water is pumped through the filter 10 in an opposite direction.
  • water is pumped from the second fluid port 42, through the central flow tube 14 towards the annular filtering chamber 18.
  • the water flow encounters the vortex generator 20.
  • the backward water flow causes the flapper valve 28 of the vortex generator 20 to close so that water cannot flow through the openings 30.
  • the water is instead directed through the curved water channels 52 of the spiraling arms 32.
  • the base 22 of the vortex generator 20 includes support structures 58 ( FIG. 3 ) that support the flapper valve 28 when water is flowing through the filter 10 in the reversed back flushing direction.
  • the support structures 58 include annual walls or rings concentrically located in relation to one another.
  • the support structures 58 support a central region 60 ( FIG. 2 ) of the flapper valve 28 whereby an outer region 62 of the flapper valve 28 seats and seals against an annular portion 64 ( FIG. 3 ) of the base 22.
  • the water channels 52 of the arms 32 define the only flow passageway for water flowing through the filter housing 12 (i.e., from the second fluid port 42 to the third fluid port 44), as the flapper valve 28 completely closes the openings 30.
  • the present vortex generator 20 having the openings 30 and the flapper valve 28 maximizes filtration efficiencies by increasing water flow through the filter 10 during normal filtering operations, and provides a spiraling high pressure vortex that maximizes the effectiveness of back flushing operations.
